constantly check temps and humidity throughout the day. Make sure things don't go to far out of range. Sometimes you get a surprise and find out that hot air from the furnace is coming up the back of the counter, or light from the window hits the tank at a certain time and temps swing. Humidity can be your problem with a glass enclosure, so you may need to cover most of the ventilation on your top. I usually run a tank for a week, looking for temp and humidity swings. Try getting a thermometer/hygrometer combo that records highs and lows so you can make sure that the tank isn't getting out of whack when you cannot look at it. The most important thing, in my opinion, is to have the husbandry correct before the snake is put in the cage, because moving things around in the first few weeks can stress a snake when it is acclimating.

Great job trying to get everything sorted before you get a snake. Your approach is so much better than the "buy a snake try to figure things out" approach we see so often. You are going to be a great keeper, and we all look forward to helping you as much as possible.
